Closing the wallet clears the send flow and can make generated eCash tokens unrecoverable

[keshav0479]

I accidentally clicked outside the wallet after generating an eCash token and noticed that the whole send screen resets when the wallet is opened again.

I tested it with a 10 sat token. The generated token disappeared from the UI after closing and reopening the wallet.

I had copied the token first, so I was able to import it again and recover sats. Otherwise, I would not have had a way to access it again.

The reset also clears the entered amount and any other in-progress send state. Since clicking anywhere outside the popover closes it, this is easy to trigger accidentally.

Steps to reproduce

1. Open the wallet
2. Go to Send > eCash Token
3. Enter an amount and click Generate Token
4. Click outside the wallet before copying the token
5. Open the wallet again and return to Send > eCash Token

Expected behavior

Closing and reopening the wallet should preserve the current send flow, including entered values and any generated or in-progress payment details.
A generated eCash token should remain recoverable until the user explicitly discards it or confirms that it has been copied.
